+Share your Local Server with a Friend
+-------------------------------------
+
+`Localtunnel <http://progrium.com/localtunnel/>`_ is a neat tool you can use to
+quickly share your local Flask server to a friend.
+
+To install Localtunnel, open a terminal and run the following command::
+
+    sudo gem install localtunnel
+
+Then, with Flask running at ``http://localhost:5000``, open a new Terminal window
+and type::
+
+    localtunnel 5000
+    Port 5000 is now publicly accessible from http://54xy.localtunnel.com ...
+
+*(Get a*  ``gem: command not found``  *error? Download RubyGems*
+`here <http://rubygems.org/pages/download>`_ *.)*
+
+If you load the URL given in the localtunnel output in your browser, you
+should see your Flask app. It's actually being loaded from your own computer!
+
+Deploying to a Web Server
+-------------------------
+
+`Heroku <http://www.heroku.com>`_ offers a free web platform to host your
+Flask app, and is the easiest way for you to put your Flask app online.
+They have excellent instructions on how to deploy your Flask app `here
+<http://devcenter.heroku.com/articles/python>`_.
